FIELD: chemistry.
SUBSTANCE: invention relates to coating composition containing a film-forming polymer containing active hydrogen-containing functional groups; a blocked polyisocyanate curing agent containing a blocking group derived from a blocking agent containing an alpha-hydroxyamide, ester or thioether; and a curing catalyst which does not contain tin, lead, iron, zinc or manganese. Invention also discloses coatings, coated substrates and methods of coating deposition on a substrate.
EFFECT: invention enables to obtain coating compositions which harden at low temperatures.
